The invention relates to a data transmission network system based on mobile communication. The data transmission network system comprises headquarter CPE terminal equipment and a headquarter application server group which are deployed in an enterprise headquarter and are in communication connection, branch CPE terminal equipment deployed in an enterprise branch, and an operator base station, and the headquarter CPE terminal equipment, the operator base station and the branch CPE terminal equipment are sequentially in communication connection to form a wireless communication link. Compared with the prior art, the method has the advantages that the existing network architecture of a user does not need to be changed, the user can plug and play after getting the configured CPE terminal equipment, the delivery is simple and convenient, and the safety is high.

The application discloses an alloy steel cutter material and a preparation method thereof. The alloy steel cutter material is composed of at least two kinds of heterogeneous steel powder, including high-carbon high-chromium alloy steel powder and medium-carbon stainless steel powder. The high-carbon high-chromium alloy steel powder contains 0.95-1.10 wt% of C, 13-15 wt% of Cr and 3-5 wt% of Mo, and the medium-carbon stainless steel powder contains 0.45-0.75 wt% of C and 12-14 wt% of Cr. The average particle size D50 of the powder is 50-80 mu m, and the microstructure of the alloy steel cutter material includes ferrite and / or martensite matrix, and also includes dispersedly distributed carbide. The alloy steel cutter material can realize continuous and clear patterns, high light-dark contrast, high hardness, high sharpness, high durability and excellent corrosion resistance.

The utility model discloses a device for PBT packing transformed from a PBAT packing device, and relates to the technical field of packing machines, the device comprises a guide rail between a sewing machine and a sealing machine, an inverted bag conveyor clamping mechanism and a tray bin, the guide rail takes a pair of guide strips as a main body, the inner sides of the pair of guide strips are provided with smooth surfaces, and the outer side of the pair of guide strips is provided with an inverted bag conveyor clamping mechanism. A pair of guide strips is arranged on the upper portion of the tray bin, a pair of reinforcing ribs is connected to the vertical centers of the outer portions of the guide strips, a plurality of clamping plates are connected to the upper portions of the outer sides of the guide strips, a pair of clamping pieces are installed on the bag falling conveyor holding and clamping mechanism, and channel steel is symmetrically installed above a tray frame of the tray bin. The distance between the clamping plates is influenced by adjusting the tightness of the bolts so as to change the distance between the guide rails, so that the guide rails ensure that the bag mouth of the material bag passes through the sewing machine upright with the most appropriate force, and the problems of sealing failure and thread breakage of the sewing machine caused by lodging of the bag mouth of the material bag are solved.
